• To produce polycrystalline superconductor ceramics with potentially higher critical currentws by eliminating grain boudary weak links caused by grain orientation misfit, we use a method combining grain shape alignment and magnetic field alignment by orthogonal alignment forces. Continuing this work, we report here X-ray diffraction data demonstrating the first preparation of an 〜80μm thick Bi_2Sr_2Ca_<0.7>Yb_<0.3>Cu_2O_x film having substantial biaxial grain alignment; a very high degree of c-axis alignment is combined with > 30% preferential <100> axis alignment within the a-b plane (relative to a random <100> axis distribution in that plane). While films with this coposition are not good super-conductors, they demonstrate the feasibility of the method.
